Re: Farting or groaning noise from climate control system

In the upper right hand corner there is a Search box, put in "Farting Noise"
and click on appropiate links. I'm sorry I cannot find my posts on this either.
Good Luck, I have done this twice, one on each car.
It worked GREAT, and Kept on working...
The Jist of this is: what DarkMingBlueSTS, says above,
Remove the glove box, and lube the actuator arms.
Do IT once , and it's done.
Have fun.

Re: Farting or groaning noise from climate control system

Old thread, I know. But, the 2005 STS 1SG I just bought a couple months ago has apparently been "fartin" around for over 10 years as the previous owner never got this fixed.
Thanks to these threads and AllData, I spent $15 on the repair kit (a new actuator arm, rotation pin, and grease) and did the repair myself.
Super quiet recirculation/fresh air cycling now!
Just for future forum members... this repair is best done according to the TSB, replacing the actuator arm and rotational pin. Simply greasing it up is a temporary fix.
And it's super easy if you just go ahead and unbolt then lower the air intake box. It was only held in by three 10mm bolts and that makes the actuator completely accessible.
